[HOWTO] Increase/Change Resolution of Mac OS X Leopard inside VirtualBox

I have installed iATKOS S3 v2 inside VirtualBox running on Debian. It can be simply installed like any other Operating Systems, but if you choose Operating System as Mac OS X Server, you must uncheck Enable EFI in the settings dialog.

If you wish to install, make sure to install latest VirtualBox (at least v3.2.x) first.

After the installation is ready, I was having problems with resolution. The only resolution that was available was 1024×768. To change it, I performed the following process.

I. Change com.apple.Boot.plist
1. Open up Finder from the dock (left most icon by default).
2. Open the Partition where you have installed Mac OS X under Devices.
3. Now, if you have an Extras directory in root, look for com.apple.Boot.plist. If you don’t, go to /Library/Preferences/SystemConfiguration/. You should see com.apple.Boot.plist
4. Copy the file com.apple.Boot.plist to Desktop.
5. Open the file on the Desktop with text editor (TextEdit).
6. Look for the following text:


If this value exists, the next line should have something like this:


Change it to whatever resolution your monitor supports.
If the value does not exist, add the following before </dict>

        Graphics Mode

Make sure, you have entered proper resolution for your monitor.

The following is my complete com.apple.Boot.plist:

	Kernel Flags
	Boot Graphics
        Quiet Boot
        Graphics Mode

7. Save the file to Desktop and close TextEdit.
8. Now, drag the file on the Desktop to the folder you copied it from. Confirm to Authenticate and Enter your password. Confirm to replace file.
9. Shut down Mac OS X.

II. Add Custom Video Mode as extradata to VirtualBox Configuration
1. Note your Virtual Machine Name for Mac OS X and quit VirtualBox. It is the name displayed in the Left Pane of the VirtualBox window.
2. Now, open up Terminal (or command prompt if you are using Windows) and run the following command (not as it is, make sure to make modifications. See below):

VBoxManage setextradata "Virtual Machine Name" "CustomVideoMode1" "_required_X_resolution_X_colordepth"

For example, if you have a virtual machine named “Mac Test” and want to set a resolution of 1440×900, you must run the following command:

VBoxManage setextradata "Mac Test" "CustomVideoMode1" "1440x900x32"

Now, start VirtualBox and start the Virtual Machine, Mac OS X should now use the new resolution.

Hope this helps.

[HOWTO] Enable “Mark All Upgrades” in Synaptic on Linux Mint

If you are using Linux Mint Gnome or Linux Mint Debian Edition, you will notice that Ctrl+G or Mark All Upgrades is disabled. This has been done to prevent users from installing upgrades that have not been tested and verified to work by Linux Mint team. Read more in this discussion.

However, if you can take care of your packages and the problems that may arise, you may want to enable the handy feature. It can be done by following the instructions below.

Open up the terminal and remove synaptic completely:

sudo apt-get purge synaptic

Then edit out the line in the following file or remove it completely. However, if you want to be able to enable it, it is recommended to just disable the line using a # in the beginning of the line.


To edit it, you can open in any text editor as root. For example, to edit it using gedit, you may press Alt+F2 and enter the following:

gksu gedit /etc/linuxmint/adjustments/10-mintsystem-synaptic.overwrite

Make sure the line looks like the following by adding a # in the beginning of the line:

#/usr/lib/linuxmint/mintSystem/adjustments/synaptic.glade /usr/share/synaptic/glade/window_main.glade

Save the file and exit.
Then, install synaptic again:

sudo apt-get install synaptic

While removing Synaptic, note the packages being removed and install them back:

sudo apt-get install aptoncd apturl jockey-gtk mint-meta-gnome mint-meta-main mintupdate

That’s it. Open up synaptic and you should be able to use “Mark All Upgrades” again.

If you wish to disable the mark all upgrades again, just remove synaptic and then remove the # from the same file and save it. Then, re-install synaptic again.

Hope it helps.

[HOWTO] Setup a Live Testing Environment for Ubuntu Daily Builds right from the Harddisk

If you are keen about the changes in the next version of Ubuntu, 11.04 (Natty Narwhal), and want first hand experience, you can setup your own live testing environment which boots right from the harddisk. You can of course test the ISOs in Virtualbox, but if your card is not supported for Virtualbox 3D, you won’t be able to test the new Ubuntu Unity interface.

Computer running Linux with Internet Access
The computer must have graphics card supported by default by Ubuntu

I am assuming you are running another copy of Ubuntu. If the instructions don’t actually fit with your system, feel free to do whatever applies to your distro.

Getting the latest CD Images
Ubuntu 11.04 Natty Narwhal is under heavy development. The CD images are updated daily for users and developers to test. They are available here. However, if you download full ISO images daily, you will be wasting a lot of data transfer and time. Instead, you can download the changes only using zsync. Here is how.

Open up the terminal and install zsync:

sudo apt-get install zsync

Now, go to the daily images page and look for .zsync files of the ISO you want to try. For instance, if you want to try Ubuntu 11.04 32bit, you will need the zsync file natty-desktop-i386.iso.zsync. Don’t download the zsync file though. You will just need the URL to the zsync file. To get that on Firefox, right click and click “Copy Link Location”.

Now, you will need a directory where you want to download the images. Create a directory and make sure about 2 GB of space is available in the drive. Then, just open up the terminal and change to that directory and type in the following:

zsync http://cdimage.ubuntu.com/daily-live/current/natty-desktop-X.iso.zsync

where X is one of amd64+mac, amd64, i386, powerpc+ps3 or powerpc.
(The second part of the above command is the link you copied in the above step.)

Now, whenever you wish to get the latest Ubuntu ISO image, just run the same command from the same directory and your ISO will be updated. zsync will download only the changed parts from the server and the download will require less data transfer and hence will be faster.

Setting it up to boot
When you have the latest ISO, you will need to test them by booting. As I mentioned earlier, you could use Virtualbox but it may not support your graphics card for 3D and hence testing Unity may not be possible. Another program you can use is “Startup Disk Creator” (also known as usb-creator-gtk), but it only lets you create USB disks. If you have USB disks and don’t mind writing lots of files to it on a daily basis (assuming you will be testing all the daily builds), you could use that. However, USB Flash drives are prone to failure if used in that way.
The program we are going to use is unetbootin. It allows you to setup booting ISOs right from the Harddisk. It is available in the repositories in most Linux distributions but the latest version may not have hit the repositories yet, so it is recommended to download it from the official page. But it is recommended to install the one from your repositories too so that the dependencies are installed.

Make it executable by doing a chmod +x or by right clicking the downloaded file and selecting properties and checking the “Allow executing file as program” in Permissions tab.

Now, launch unetbootin and select the DiskImage option (and not the distribution) and browse to locate the latest daily ISO you downloaded using zsync. Select Type as Hard Disk and Drive as / and click OK.

When done, reboot and hold on Shift when the computer just starts to bring up the Grub menu. In the Grub menu, select the “Unetbootin” entry (and not the other ones, they may not work).

To setup the latest downloaded ISO again, run Unetbootin and uninstall the existing entry and repeat the same process.

Note: If you are using this setup, skip any updates to grub.

Happy testing.

[SOLVED] Compiz text input problem in Ubuntu 11.04 Natty Narwhal Alpha 1

If you are using Ubuntu 11.04 Natty Narwhal Alpha, you may face compiz crashes. To recover from compiz crash, you can do a

compiz --replace

, but sometimes, you are not able to input text any more so doing that is not possible. Then, all you can do is restart the system. However, compiz can be restarted from other terminals. If you encounter a crash and are no longer able to input text, press Ctrl+Alt+F1 and login. Now, type in the following:

DISPLAY=:0.0 compiz --replace

Now, when you press Ctrl+Alt+F7, you will see that compiz has restarted and you can type text again. If some components (like unity) fail to load, bring up the terminal by pressing Ctrl+Alt+T and type in

compiz --replace

to load compiz again.

If it does not work, login to the terminal (Ctrl+Alt+F1-F6) and remove the compiz settings directory from your home directory. Here is how you do that:

mv .compiz-1 compiz-old

Now, restart compiz:

DISPLAY=:0.0 compiz --replace

Hope this helps.

[HOWTO] Enable Alt+F2 in Ubuntu Natty 11.04 Narwhal Alpha 1

If you have installed Ubuntu Natty Narwhal Alpha 1, you will notice the new Unity interface and hence no Gnome Panel(s) anymore. Since “Run Application” dialog is a part of gnome-panel, it is not possible to enable the same “Run Application” dialog. If you wish, you can achieve that by running the gnome-panel, but this is not the recommended course of action if you wish to keep running unity.
So, the other way to make it work is to use third party run dialogs from repositories. One of the best run dialog is gmrun. It is available in Ubuntu universe repositories. Open up the terminal (by pressing Ctrl+Alt+T) and type in the following to launch Synaptic Package Manager:

sudo synaptic

Then, go to Settings>Repositories and Enable the Universe repository.

After having done that, close the repository window and synaptic. In the terminal, type in the following:

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install gmrun compizconfig-settings-manager

Now, lets launch compizconfig-settings-manager. Just type in the following in the terminal:


Search for commands and enable it. Click on Commands to set commands and Key Bindings. In Command line 0, type in gmrun and in Key Bindings tab, click on the Disabled button and check Enable to Enable it. Press the Grab key combination button and press Alt+F2. In the dialog that pops up, click “Disable Run Applications”.

If all goes well, you can now press Alt+F2 and a “Run Program” dialog will pop up. You can use tab to complete fields and press Ctrl+R to search older run entries.

Hope this helps.

[HOWTO] Disable Unity Interface and restore original (classic) interface in Ubuntu Natty Narwhal

Unity interface is the default interface in Ubuntu 11.04 Natty Narwhal. It consists of the dock and launchers. However, if you don’t like the dock, animations and the interface as a whole, you can just disable it and login to Ubuntu Classic Desktop.

Logout and type in(or select) your username and in the bottom panel, select “Ubuntu Classic Desktop” instead of “Ubuntu Desktop Edition”. When you login next time, the same will be selected by default.

To re-enable Unity interface, just select “Ubuntu Desktop Edition” during login.

Compiz in November 27 daily build of Ubuntu 11.04 Natty Narwhal

I just used zsync to download the latest daily build of Ubuntu 11.04 Natty Narwhal. It features Ubuntu Unity Plugin for Compiz among other changes.

Compiz version is 0.9.2 and it features several plugins by default for functionality and effects. However, extra plugins are not available in current repository (0.8.6 version is available, which breaks 0.9.2)

Clicking the Workspace Switcher icon on Unity brings up Expo interface and it is easy to switch to another workspace and move windows between workspaces.

You can enable autohide in Unity by installing compizconfig-settings-manager:

sudo apt-get install compizconfig-settings-manager

After it is installed, you can launch it by pressing Alt+F2 to bring up the Run Application Dialog and then typing in ccsm.

The hidden unity dock can be brought back by putting mouse over the Ubuntu icon in the top left corner.

It also features a global menu (indicator-appmenu) which removes the menu bar from the applications and puts it up on the top panel. The menu shown is the menu of the application in focus. This feature is similar to Mac OS X. However, only GTK Applications are supported currently. This means, Openoffice and Firefox are not supported till date.

The current interface lacks an easy way to launch applications (it has to be done via Alt+F2 if compiz is enabled), compiz crashes a lot, sometimes when opening up Appearance Preferences, sometimes when changing compiz settings and sometimes just while doing something arbitrary.

Currently compiz in Natty is far from being perfect, but this is quite some change considering the fact that even the final relase is scheduled in April 28, 2011. The first alpha however, should arrive shortly and hope we see something better.

[SOLVED] “Error: Dependency is not satisfiable: libnautilus-extension1 (>= 1:2.22.2)” while installing dropbox

I downloaded nautilux-dropbox Ubuntu deb package from Dropbox Linux Download Page. When I tried to install it via gdebi deb installer in Debian, I got the following error:

Error: Dependency is not satisfiable: libnautilus-extension1 (>= 1:2.22.2)

If you add repos and try to install it from there via Synaptic, you will get the error:

Depends: libnautilus-extension1 (>=1:2.22.2) but 2.30.1-2 is to be installed

If you install it with dpkg -i, you will get the following error:

Selecting previously deselected package nautilus-dropbox.
(Reading database … 229404 files and directories currently installed.)
Unpacking nautilus-dropbox (from nautilus-dropbox_0.6.7_i386.deb) …

Errors were encountered while processing:

Using the dpkg method will result in broken packages.

I had downloaded the version 0.6.7 32 bit (i386) i.e. nautilus-dropbox_0.6.7_i386.deb and was unable to install it cleanly. However, when I ran it by force installing, it ran without problems but the package was broken. So, the problem was not with the unmet dependencies but the deb file wrongly specifying dependencies.

So, I decided to fix the deb file. I unpacked the deb:

mkdir -p extract/DEBIAN
dpkg-deb -x nautilus-dropbox_0.6.7_i386.deb extract/
dpkg-deb -e nautilus-dropbox_0.6.7_i386.deb extract/DEBIAN/

Then edited the extract/DEBIAN/control file with gedit. You can use any other text editor of your choice.
The “Depends:” line looks like the following:

Depends: libatk1.0-0 (>= 1.20.0), libc6 (>= 2.4), libcairo2 (>= 1.6.0), libglib2.0-0 (>= 2.16.0), libgtk2.0-0 (>= 2.12.0), libnautilus-extension1 (>= 1:2.22.2), libpango1.0-0 (>= 1.20.1), python (>= 2.5), python-gtk2 (>= 2.12)

Notice the entry “libnautilus-extension1 (>= 1:2.22.2)”. In my installation, the version of libnautilus-extension1 is 2.30.1 and not 1:2.30.1 (which is the version format for libnautilus-extension1 in Ubuntu). So, I edited the version number to 2.22.2 instead of 1:2.22.2. So, the new depends line looks like the following:

Depends: libatk1.0-0 (>= 1.20.0), libc6 (>= 2.4), libcairo2 (>= 1.6.0), libglib2.0-0 (>= 2.16.0), libgtk2.0-0 (>= 2.12.0), libnautilus-extension1 (>= 2.22.2), libpango1.0-0 (>= 1.20.1), python (>= 2.5), python-gtk2 (>= 2.12)

After the change, create a directory called build and run the dpkg-deb command with -b switch to build the new deb file:

mkdir build
dpkg-deb -b extract/ build/

You will find a deb file in build/ directory which should install without dependency problems.

After installing, install the service by running the following as root and you are all done:

dropbox start -i

Hope this helps.

[HOWTO] Install Greasemonkey Firefox Addon in Firefox 4

I have installed Firefox 4 in my Debian Testing installation from Launchpad PPA. It is quite stable and I have decided to use it instead of Firefox 3. Most of the addons I used is compatible with Firefox 4 by now. However, the version of Greasemonkey available in Mozilla Firefox Addons Site is not compatible with Mozilla Firefox v4 latest build. To install the latest nightly build of Greasemonkey, I went to Greasemonkey Nightly Download and installed it. However Greasefire is not available, we can install userscripts directly from Userscripts website for now.

[HOWTO] Change Debian Testing to Linux Mint Debian Edition (LMDE)

Linux Mint Debian Edition is a rolling release distro based on Debian Testing. It is currently only available in 32bit and not for other architectures.

If you already have a Debian Testing installation, you will not have problems changing it to Linux Mint, if you wish to. This can be achieved by changing apt sources and preferences and installing Linux Mint meta packages.

Open /etc/apt/sources.list as root and append the following line at the end of the file:

deb http://packages.linuxmint.com/ debian main upstream import

If you want real Linux Mint Debian, you will need to remove other software sources like Unstable repos but have the following at least:

deb http://ftp.debian.org/debian testing main contrib non-free
deb http://security.debian.org/ testing/updates main contrib non-free
deb http://www.debian-multimedia.org testing main non-free

Now, open up /etc/apt/preferences and add the following:

Package: *
Pin: release o=linuxmint
Pin-Priority: 700

Package: *
Pin: origin packages.linuxmint.com
Pin-Priority: 700

Package: *
Pin: release o=Debian
Pin-Priority: 500

The above change will make sure that Linux Mint repos will be favored over Debian.

First upgrade your installation:

apt-get update
apt-get upgrade

Now, install the following packages:


by running:

apt-get install mint-meta-debian mint-wallpapers-extra mint-wallpapers-previous-releases

If some installed packages conflict with the new packages, remove them and try again.

Now, change the default theme to Shiki-wise, remove upper panel and add notification area, mintmenu to lower panel and you are done.
